I set up a Derbit or...

I set up a Derbit order for 4000 and canceled the 2000 Derbit order and they Derbit both orders on the first of February and I went to the store with a bank statements to request the extra 2000 they debited but they haven't refunded it back and they said it would reflect on Saturday which it didn't and they crippled me because I didn't budget for 6000 to be debited by one store when I have other commitments
